﴿ إِنَّ ٱلَّذِينَ كَفَرُوا۟ لَن تُغْنِىَ عَنْهُمْ أَمْوَٰلُهُمْ وَلَآ أَوْلَٰدُهُم مِّنَ ٱللَّهِ شَيْـًۭٔا ۖ وَأُو۟لَٰٓئِكَ هُمْ وَقُودُ ٱلنَّارِ ﴾

“BEHOLD, as for those who are bent on denying the truth - neither their worldly possessions nor their offspring will in the least avail them against God; and it is they, they who shall be the fuel of the fire!”

((On that day) neither the riches) the abundance of riches (nor the progeny) nor the abundance of progeny (of those who disbelieve) i.e. Ka'b Ibn al-Ashraf and his fellow companions; and it is also said that this refers to Abu Jahl and his companions (will aught avail them with Allah) will not avail them anything from Allah's torment. (They will be fuel for fire) they are the firewood of hell.
